This week I spoke with Pete Korzeniewski from Grundfos about distributed pumping.  I'm seeing some huge advantages to this setup but you'll have to listen to the episode to hear what they are.  I don't want to spoil the surprise and try to summarize here, listen and enjoy. . . .    If you want to get started with distributed pumping, get a hold of me.  [email protected] or 949-698-3014

This week I have Sarah Dunlop from Bosch (Florida Heat Pump) to talk about where sound comes from on WSHP's and how to mitigate them.  Sarah explains each solution and give a priority list of which options to go with first when you need to reduce the sound of the unit.  She also explains the Bosch and Florida Heat Pump partnership.  If you want to know more, email me at [email protected].  Enjoy!   

The sound levels inside occupied space is always a concern and VAW has been extremely helpful in meeting the required sound levels set by the acoustical engineer and fixing issues in the field.   Whether the solution is simply aerodynamics or sound traps, Emanuel from VAW breaks it down in this podcast.  Emanuel even discusses ultra low static pressure loss solutions!  I hope you enjoy!!!

I seem to be talking about heat recovery almost daily so I had to do a follow up podcast with Multistack to add to the modular chiller podcast (Episode #24).  I had Ed Watson define heat recovery and go through the 3 heat recovery options they have.  We talked about the water to water heat recovery, 4-pipe air source heat recovery and their VME 6-pipe heat recovery system.  We also talked about water temperature which always seems to catch engineers off guard so it was essential we went through it.  If you want to see pictures of these systems, go to Multistack.com or email me and I'll walk you through them.  [email protected] or 949-698-3014

This week I had Michael Jandrt from Multistack on the podcast to talk about modular chillers.   I have learned a lot from Michael so I wanted to share some of the things I have learned.  We talk about what a modular chiller is, the versatility, flexibility, what does N+1 look like with modular chillers, how to properly control modular chillers and the piping options (variable primary, primary secondary or constant flow).  I'll be doing a follow up next week on dedicated heat recovery with Ed at Multistack but until then, enjoy this weeks episode on modular chillers.

This week I have Dan Jones from UV Resources on the podcast.  Dan is the President of UV Resources and has seen his industry change drastically with COVID-19 so I had him talk about pre and post COVID.  UV Lights have become a household name since the media has told everyone that it can kill viruses so I had Dan explain what it actually does to the virus and how we can design HVAC systems with effective "kill on the fly" UV lights.  Enjoy and if you have an application that you'd like to learn more about, email/call me at [email protected] or 949-698-3014

This episode I talked to Kurt Krawczyk from The Whalen Company, a family owned company from Eastern Maryland.  We go through footprint, riser piping, removable chassis/coil pack, sound testing and a few more items that are unique to Whalen.  I screwed this podcast up twice before we got it right. Third times a charm and this is a great discussion on vertical stack units vs. closet style.

This week I have Kenton Hawkins from Eviro-tec to talk about fan coils.  We had a discussion a few weeks ago while going through some book specifications about what makes a fan coil or blower coil more efficient than another and so we decided to record a podcast about the items we came up with.  We talk about coil tube diameter, fin spacing, casing leakage and motor types/controls.  Kenton also gives a little teaser at the end about Enviro-Tec's 6-way valve.  We'll do another podcast on this soon.  I hope you enjoy and get something usefull from this podcast!  If you want more info . . .

This week I got with Robert Boozer from Semco and we discussed chilled beams.  We went through the basics and talked about some of the design mistakes that we see.  I let Robert do a explanation on how Semco is different from other chilled beams.  This is important since it can save energy, simplify design and speed up installation during construction.  Contact me if you want to learn more and discuss chilled beams.  [email protected]
